Do text compression tests qualify winRar or 7zip as intelligent?
The paper suggests an alternative test to the famous Turing test, which tests a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human.
In this test, if winRar or 7zip will compress a file similarly to how a human would compress a file (how does a human compress a file?!), then, yes, those programs will pass the test and will be considered intelligent.

... thus compression ratio on a standard benchmark corpus could be used as an objective and quantitative alternative test for AI (Mahoney, 1999).
